STOP-MOTION FOR WINDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 728,983, dated May 26,1903.

Application filed June 27, 1902. Serial No. 1l3 485. (No model.)

T0 all whom, it may concern-.-

Be it known that I, THOMAS HENRY RUSH- TON, machine-maker, a subject ofthe King of Great Britain, residing at Kay Street Works, Bolton, in thecounty of Lancaster, England, have invented certain new anduseful-Improvements in Machines for Winding Yarns and Threads ofCotton,'Flax, and other Fibrous Materials, of which the following is aspecification.

My invention relates to improvements in machines for winding yarns andthreads of cotton, flax, and other fibrous materials; and the objects ofmy improvements are to simplify and cheapen the construction and toeconomize floor-space.

In the accompanying two sheets of drawings, Figure 1 is a sectionalelevation, and Fig. 2 is a plan, of part of a winding-machine to whichmy improvements are applied. Fig. 3 is an enlarged detail side view ofparts in Fig. 1. Fig. 4 is a plan of Fig. 3 with a few additional partsnotincluded in Fig, 3. Figs. 5 and 6 represent details.

In the'views, 1 denotes the stand or frame of the machine, 2 the cop boxor rail, 3 the cops, 4 the cop-skewer brackets or supports, 5 the rodupon which the cop-skewer brackets are fixed, 6 the stationarythread-guides, 7 the drag-board, 8 the pivoted needle-box, 9detector-needles, 1O rotating wiper-shaf t, and 11 a guide roller,pulley, or rod, all the foregoing parts being of the ordinaryconstruction and operating in the usual Way, as Well understood.

According to my improvements I dispense with the usual longitudinalrails, and I employ one central rail 12, on which are mounted forkedbrackets 13, supporting the driving drums 14, which are driven in theusual way by suitable gearing. (Not shown.) This construction andarrangement of one central supporting-rail 12 enables the drivingdrums14 to be brought much closertogether than in an ordinary frame, and soeconomizes fioorspace. I also dispense with the usual intermediaterollers or wood blocks and instead drive the flangeless bobbins 15direct from the drums 14. Consequently the traverserods 16 on theopposite sides of the frame for the thread-guides 17 are brought muchnearer together than usual, whereby further floorspace is saved. I

The'bobbins 15 are supported in improved carriers, each of whichconsists of a pair of arms 18, mounted upon a stud 19, supported in abracket 20, carried by the central rail 12, and the bobbins 15 are heldnormally up to their driving-drums 14 by means of weights 33,- suspendedfrom extensions of the arms 18, secured adjustably on the studs 19. (SeeFig. 3.) The arms 18 are secured adjustably by means of screws 21 uponthe studs 19, each of which is long enough to enable the arms 18 whenfixed at its extremities to take the longest bobbin, and by looseningthe screws 21 and bringing the arms 18 nearer together and then fixingthem in position they can be adjusted to take the shortest or anyintermediate length of bobbin.

Each traverse thread-guide 17 is pivoted loosely upon its traverse-rod16, but is connected thereto, so as to move with the rod in itstraverse, which may be efiected in the usual way by a cam or equivalent.(Not shown.) In the drawings each thread-guide 17 is shown thus held inposition by means of a collar 29, placed between the jaws of the dividedboss of the thread-guide and fixed on the traverse-rod 16 by ascrew 22.A light spring 23 is lapped around the rod 16 and has one extremitysecured to the screw 22 and its other end bent over to rest on thethread-guide, and so cause it to bear with a slight but constantpressure upon the yarn wound upon the bobbin 15.

To stop any bobbin 1 5 on the breakage of one or more of its threads, Iemploy the pivoted needle-box 8, and in conjunction with thisstop-motion or its equivalent I employ a sliding blade 24, of thinsheet-steel or any other suitable metal or material. This blade 24 isfixed upon a vertical rod 25, fitted to slide in a stationary guide 26and connected at its lower end by a stud 27 to the slotted end of thelever 28, f ulcrumed on the bobbin-carrier stud 19. The. front end ofthis lever 28 is bent laterally and then forwardly where it restsnormally upon one end of the pivoted needle-box 8; but when a thread (orthreads) breaks or fails its corresponding detectorneedle 9 falls andcoming in contact with the toothed part on the rotating wiper-shaft 10is struck, and thereby the pivoted needle-box 8 is moved on its pivotsinthe direction of the arrow and allows the curved or slotted end of thelever 28 to fall by its own weight assisted by a spring 30. The elfectof this movement of the lever 28 is to raise the sliding blade 24, whichthereby passes up between, and so separates the bobbin from itsdriving-drum 14, and so stops the rotation of the bobbin.Simultaneouslya rod 31, Figs. 5 and 6, connected to the vertical slidingrod 25, is also raised, and its upper horizontal portion coming incontact with the pivoted traverse thread-guide 17 turns it upward andback clear of the bobbin 15 until it bears against the stationaryguide-rod 32, over which the threads pass from the roller or equivalent11 to the traverse -guide 17 and bobbin 15. When the lever 28 is raisedby hand into the position shown best in Fig. 3, the sliding blade 24 iswithdrawn, and the bobbin 15, being again in contact with itsdriving-drum 14, is restarted, and the rod 31 being also drawn down thetraverse thread-guide 17 is automatically replaced by gravity and spring23.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be operated, I declare thatWhat I claim, and desire to secure by Letters Patent of the UnitedStates, 1s-

1. In combination in a winding-frame, a single central rail, a series offorked brackets therefrom to move the traverse thread-guide out of theway, all substantially as herein described and as illustrated by thedrawings.

2. The combination with a pivoted needlebox forming part of astop-motion, a sliding blade connected with and controlled by the saidneedle-box, of a loosely-pivoted traverse thread-guide arranged to bearnormally on the yarn or its bobbin and on the breakage of a thread to beraised out of the way, means for raising the said thread-guide, adrivingdrum for the bobbin and the sliding blade actuated from the saidstop-motion to separate the bobbin from its driving-drum, allsubstantially as herein described and as illustrated by the drawings.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
